Symptom Clusters of Neuropsychiatric Symptoms in Mild Cognitive Impairment and Their Comparative Risks of Dementia: A Cohort Study of 8530 Older Persons

Neuropsychiatric symptoms (NPS) have been recognized to increase the risk of dementia among individuals with mild cognitive impairment (MCI). However, it is unclear whether the risk is shared across the various NPS or driven primarily by selected few symptoms. This study sought to provide confirmatory evidence on the comparative risk of dementia across the various NPS in MCI.
